24 Claims.

The present invention relates to textile machinery and more particularly to mechanism such as spooling machines or so -called yarn setting frames, for the preparation of yarns for weaving, as in Axminster and other carpet or like looms. It aims to provide improved mechanism of the class and for the purpose described, and in which the accurate and rapid handling of the yarns and the conditioning of the machine are facilitated, together with other improvements which will be apparent from the accompanying description and drawings.

Referring first to Figs. 1 and 2, we have there shown a textile machine in which the improvements of our invention may be embodied, the machine illustrated being typical of so-called spoolers or yarn setting frames, for winding tufting-yarns onto a spool, in the desired pattern arrangement. In certain respects the improvements of our present invention are particularly adapted for use with such machine. That shown comprises a frame I supporting a main or drive shaft 2 to which power may be applied as through the series of pulleys 3, Fig. 1. Suitable shipper mechanism 4 is provided including a shipper rod 5 and shipper lever 6, Fig. 2, by which the operator may control the machine, to impart winding movement to a spool l, in either direction at will, or to stop the machine.

The yarns, coming from bobbins (not shown) are taken on to the spool l, which is removably supported for winding movement, between releasable rotary members engaging its opposite ends and operatively connected with the drive shaft 2 through suitable gearing, including the pinion 8 and gear 9, Fig. 2. A series of friction rolls III, ll, [2 engage the periphery of the spool in its winding position and are supported for bodily yielding movement away from the spool as the wound-on yarn builds up. The rolls are pressed against the spool during its winding, so that the yarns are wound evenly and tightly and in the same order or pattern-arranged condition as is provided for the reed or yarn-separating device upon the machine.

To provide for such movement of the rolls, the upper friction roll it is carried on an arm l3 pivoted at M and having a hooked link l5 releasably engaged with its opposite end, said link being connected at its lower end to a weighted pivoted lever iii. The rear friction roll H is mounted on a weighted arm ll, while the third roller 12 may be similarly movably supported. This positioning and releasing mechanism for the friction rolls, by which they are pressed against the spool, during winding, and are adapted to be opened out or released from the spool, for removal or insertion of the latter, also includes a roll releasing shaft i8 having crank and link connection with a weighted lever l9 fulcrumed on the machine as at 26 and connected by a link 2| with the pivot i l of the arm of the top roll. On the same releasing shaft I8 is a second arm 22 carrying a cam roll 23 on which rests the weighted lever [5. Turning of the roll release shaft, in a counter-clockwise direction as viewed in Fig. 2, serves to open out the friction rolls, through the linkage system of which portions have been referred to above and appear in Fig. 2.

Theyarns to be wound are passed through and separated by a reed or separator upon the machine. intermediate the bobbins or source of yarn supply and the spool. After winding of the spool, the yarn ends are held in the same spaced relation by a portable transfer comb, spacer or yarnend clamp, the spooling machine having provision for supporting such spacer or clamp and for applying it to the yarns. These spacers or clamps, on completion of the winding operation, are temporarily attached to the respective spool so that the latter may be removed and stored in quantities for subsequent use. It is with the yarn guiding and separating portions of the spooling mechanism, including the reed, the holder for the yarn-end clamp or transfer comb, and their associated parts and operating means, both individually and in their relation to the machine as a whole, that our present invention is mainly concerned.

Referring now to Figs. 1 to 10, there is provided at the upper rear portion of the machine, as seen at the left in Fig. 2, a cross piece 25 supported by brackets 21, 28 and carrying a yarn bar or platform 26. The yarns coming from the creel or other yarn source pass transversely over the platform 26, through the reed or separating guide previously refered to, and thence to the spool l.

The reed comprises a multiplicity of dents or elements 3!] extending across the machine, over the full width of any series of yarns to be wound, said dents and their mounting as herein illustrated being of novel construction.

As best seen in Figs. 3, 3 and 4, the dents are of a general blade-like form, being stamped, out or otherwise formed from suitable sheet metal or other material. Each comprises a main or body portion 3! preferably having a substantial ex tent in the direction of the yarn travel, so that relatively elongated yarn guide passages are provided between adjacent dents, as contrasted, for example, with the mere separation afforded by a series of pins or pegs.

Each dent has a mounting portion or tang 32 whereby it is adapted readily to be mounted in fixed position, or to be individually removed. The dents are thereby detachably set in a mounting bar or element 33, herein including upper and lower flanges 34 and (:5 having aligned series of slots or dent-receiving formations 36 and 3? respectively. The tangs of the dents, of reduced width, are adapted to be set into said vertically aligned receiving formations 36 and 3?, and the body portions of the dents have each a shoulder 38 for seating on the upper flange, positioning of the dent tangs 32 are of further reduced width, as indicated'at 39, providing a lower shoulder 40 adapted to seat on the lower flange 35, further positioning and supporting the dents. The two series of receiving formations 36 and 31, and the tangs or mounting portions 32 of the dents are preferably so proportioned that the latter have a supporting fit in said formations, with their rear edges 4! in engagement, or substantial engagement, with the mounting bar 33, so that they are held against undue lateral movement in -all directions.

Means is also provided for removably retaining the dents against unintentional upward withd rawal. For this purpose each dent tang 32 has formed in it a notch 42 adapted to receive the lateral rib 43 of a detent M extending along the reed and suitably secured as by screws to the cross bar 25 or to a lateral extension 45 thereof. The detent e4 may be formed as one piece extending the full length of the comb or may comprise a number of sections, and it is preferably of sufficiently resilient material so that it may be sprung outwardly, to release any desired dent or a plurality thereof. The mounting bar 33 is itself detachably screwed or otherwise held in fixed position upon the cross bar 25.

The upper portions of the dents are preferably of a somewhat rounded and tapering form substantially as illustrated, to facilitate the initial positicring of the yarns or yarn groups between them. The dents also are desirably equipped with means for preventing unintentional vertical upward escape of the yarns. For this purpose we have illustrated, see particularly Figs. 3 and 4, a laterally deflected nib or barb ie at an upper portion of each dent, each such element being offset from its dent, toward the next adjacent dent, so that it crosses or substantially crosses the interdental space. These barbs or lateral projections i5 prevent the yarns from escaping upwardly during ordinary use of the machine but permit them to be removed in that direction, by intentional bending or deflecting of the yarn about the barb. The upper edges of the projections or nibs to are desirably inclined downward- 1y, as indicated at ii, to facilitate manual or other broadwise insertion of the yarns between the dents.

In combination with the described reed we desirably provide means for readily identifying any dent or any interdental space of the reed, as an aid to the initial setting up of the yarns and to facilitate the proper re-laying of a yarn which might become broken or whose supply runs out.

as indicated to facilitate reading of the scale."

In order also readily to distinguish or identify a particular dent of the reed or particular section thereof including a plurality of dents, we also may provide means for visually distinguishing or differentiating some of the dents, in a regularly recurring or other order, as, for example, every sixth dent, or by any other desired grouping thereof. As one convenient form of such them vertically. As illustrated, the lower ends visually differentiating means we have illustrated 75 some of the dents, each sixth one in the particular arrangement shown, and also the outer dents of the reed, as provided with a marker or marking portion. herein projecting upwardly above the main level of the reed, and clearly demarking the same into a plurality of sections or multiple dent units. These markers may also be individually distinguished by color means thereon, to correspond with the yarn color of the section of dents marked by them, or otherwise. By reason of the demo-untable and readily assemblable individual mounting of the dents, including these marker dents, the position of the markers can readily be shifted or rearranged to suit different pattern requirements.

As previously stated, the yarns when wound upon the spool then have their ends separably held in their position as wound, during subsequent handling and storage of the spool until it is to be used in a loom. This is accomplished by means of a portable transfer comb or yarn-end clamp, one type of which is seen at 53 in Figs. 2, 4, 5, 8 and 10. The setting frame or spooling machine as herein shown includes means for holding such transfer comb in proper position relative to the series of yarns, and for applying the comb to the yarns upon completion of the winding operation.

Such means herein includes a comb holder or holder bar 54 formed with a U-shaped seat 55, see Fig. 4, for a. comb. This comb holder is mounted upon the machine for vertical movement relative to the reed and to the yarns. In Figs. 5 and 6 it is seen in its normal or down position, while in Figs. 2 and 4 it is shown elevated to bring the teeth of the comb supported thereon up between the series of yarns, for applying the comb to them. At its ends the comb holder 54 is guided for such vertical movement in ways formed in the vertical guides 56, 56 suitably mounted as upon the cross bar 25; see particularly Fig. 10. The comb holder 54 may be accurately positioned and adjusted longitudinally as by means of an adjusting guide or block 51, one at each end, and adjustably mounted on the holder as by means of the bolt and slot connection 58, Figs. 7 and 8. The outer end faces of the guide blocks 51 are adapted to have positioning engagement with the vertical guides 56, thus adjustably positioning the comb holder lengthwise.

A transfer comb such as seen in Figs. 4, 8 and 10 is positioned for application in the seat 55 of the holder. The transfer comb as here shown for the purposes of illustration is of the type to which a yarn retaining cap (not shown), is subsequently applied, the combbeing equipped with clips 53a for securing such cap, and with attaching springs 53b for temporarily holding the transfer comb on and along a spool, the springs being engaged over the spool pintles. The comb holder, for receiving this or other types of comb, as herein shown, is of a novel open-end construction facilitating cleaning of the parts. As best seen in Figs. 7, 8 and 9, the end portions of the U-shaped' comb seat 55 are expanded laterally and also deepened below the general level of the bottom of the seat, forming a cleaning pocket 59. Outwardly beyond these pockets, of which there is preferably one at each end, the comb holder is slotted vertically, providing the open slot formation 60 as seen in Figs. '7 to 10. These formations enable the comb holder to be cleaned without removal from the machine, merely by brushing any collected lint or dirt along the bottom of the comb seat 55, into one of the end pockets 59 and thence downwardly and outwardly through the adjacent end slot 60. I

Means is also provided for adjustably positioning a transfer comb 53 in its holder, to bring it accurately into the desired position or align- 5 ment with respect to the reed. For this purpose we employ adjustable comb stops or blocks 6|, located adjacent the ends of the comb seat and within the end slot 60 of the comb holder. These stops 6| may be variably positioned lengthwise of 10:

the holder, as by means of the slot and screw connection 62, and are adapted to have end engagement with the comb, positively and accurately to position the latter longitudinally with respect to the holder and also in relation to the reed.

The comb holder with a transfer comb seated therein is adapted to be elevated at the desired time, for applying the comb to the yarns, manually or automatically. The lifting means here shown by way of example includes a plurality of cam levers 63 pivotally hung as at 64 upon a front cross strip 65 extending between the vertical guides 56. The comb holder 54 seats upon the upper portions of the cam levers 63, and the lower portions of the latter are interconnected 2 as by a link 66. Operating rods 61 extend out to the side of the machine, preferably one at each side, whereby the cam levers may be swung in unison to elevate the comb holder, from its normal or lower position as in Figs. 5 and 6 to its upper yarn-applying position as illustrated in Figs.

1, 2 and 4. Stops 68 adjacent the cam levers limit the movement of the levers, in either direction.

By comparison of Figs. 5 and 6 with Figs. 2 and 4 it is apparent that the lifting of the comb holder carries the transfer comb 53 up from its previous position below the path'of the yarns, assumed during their winding, to its applied po-' sition. In so applying the transfer comb its teeth, see Fig. 8, are passed up between the yarns ex- .0 tending through the reed, so that the transfer comb then spaces the yarns and holds them in the desired distribution lengthwise the spool. The spool, yarns and transfer comb maythen be removed from the machine, the transfer comb -15 being then attached to the spool, in the manner previously described, to retain the yarn ends in their proper distributed positions during handling and storage of the spool prior to use in the loom. Difiiculty has heretofore arisen in applyas ing transfer combs to the yarns, due to improper reception of the yarns in the comb and to splitting of the yarns or groups of yarns by the comb teeth, this being true whether the yarns or socalled ends --are single strands, or, as more usual, are composed of a plurality of strands or individual yarns.

This difiiculty we have found to have been caused by inadequate positioning or guiding of the yarns during the comb applying operation, 0 and to the character of reed previously employed and the relatively large gap between the reed and the plane of comb application. From a consideration particularly of Fig. 4 it will be seen that in accordance with our invention the reed and the comb applying elements are so constructed and arranged that the comb is applied while the yarns are positively held and guided by the reed dents 30, and at or substantially in the plane of the reed or its fore portion. It will be noted that 70 the lower portions of the blades 3| oi the reed dents are recessed rearwardly as at 3la and that said guiding portions or blades 3| of the dents extend forwardly to or substantially to the plane of the comb, even, if desired, overhanging the relatively narrow portion 54w of the comb holder between the comb teeth of the reed. This close juxtaposition of the comb and the reed becomes possible, without operative interference between them, by reason of the blade-like construction of the reed dents, with their extensive guide portions lengthwise of the yarns, and the general novel formation of said dents and of their special form of mounting, all as previously described.

Obviously our invention is equally adapted for use with a spooling machine or set frame equipped with means for automatically lifting and applying the transfer comb at the end of the winding operation, such for example as shown in the patent to Edgar F. Hathaway and Charles Lea, No. 1,313,294,.of August '19, 1919, as well as in connection with the manual comb applying mechanism herein shown by way of example.

Referring now to Figs. 13 to 16, we have there illustrated a construction also embodying the principles of our invention as previously described in connection with the preceding figures, but which is particularly adapted for use in connection with the preparation of yarn spools for use in wide work, that is, where a plurality of spools are to be installed, in axial alignment, along one carrier or tube frame, for use in wide looms. In such cases it will be understood that the adjoining heads of two spools, and the spool supports upon the yarn carrier or tube frame, necessarily cause a gap between the yarn series as positioned upon the several spools. The yarn guiding passages or tubes of the yarn carrier, however, are uniformly spaced from end to end of the latter, so that in passing from the spools to these guide passages the yarns must be somewhat spread or fanned out, lengthwise the spools, as indicated by the dotted lines in Fig. 14.. In such instances, the transfer combs employed are of a length differing from and generally exceeding that of the yarn series upon the spools, and have their interdental spaces distributed in uniformity with the yarn passages of the yarn carriers or tube frames with which the spools are to be employed. The construction of Figs. 11 to 16 is particularly adapted for use where a series of yarns or the like is to be wound upon a spool which may be of a different length from that of the transfer comb or yarn-end clamp, one of the reasons for such difference in length being that just stated. In other words, the pitch or distance between the yarns as upon the spool is different from the pitch of the yarn receiving portions or interdental spaces of the transfer comb. In said figures the yarn pitch of the spool is less than that of the transfer comb, but in some cases the condition may be the reverse. Parts otherwise not specifically referred to in connection with Figs. 11 to 16 may be similar as in the figures previously described.

Referring first to Fig. 15, the reed dents 10, or some of them, are formed with laterally offset portions, as contrasted with the straight dents of Figs. 1 to 10. The distribution and manner of offset of these dents is such that their upper portions II, which function to guide the yarns during the winding thereof, are comprised within the yarn-receiving length of the spool and are spaced to distribute the yarns uniformly, or as desired, upon the spool. That is, these upper or winding-guide portions of the reed dents correspond to the guide-portions of the dents as in Figs. 1 to 10. In the present figures, however, provision is made for elevating the reed itself together with and in unison with the lifting of the transfer comb, and the offset of the lower portions of the reed dents is such as to spread and distribute the yarn series to bring the yarn spacing into conformity with that of the transfer comb. A spooling machine embodying this 5 broad principle is disclosed and claimed broadly in our previous Patent No. 1,666,650, dated April 17, 1928.

Still referring to Fig. 15 it will be understood that the reed dents T6 are offset, with the excep- 10 tion of the central dent or central series of dents, and are offset in opposite directions at the two ides of the central dent or dents. This offsetting is desirably by increments varying progressively from the central portion of the reed toward its ends so that, in the comb applying operation, the yarns are spread to the varying extents desired to bring them into the somewhat greater but uniformly spaced condition as required for the transfer comb; see the dotted line position of the yarns in Fig. 14. In the present illustration the offsetting of the reed dents is outwardly toward the ends of the reed, for widening the distribution of the yarns as compared with their position upon the spool, but our invention is equally applicable to a case in which a narrowed distribution of the yarns might be desired, in which instance the offsetting of the reed dents would be the reverse of that shown.

Referring now to Fig. 12, the dents, with the exception of the central portion of the reed, wherein they may be without offset, include said straight upper winding-guide portions H, intermediate inclined or realigning portions 12, and the lower redistributed or yarn-applying guide portion 16. The dents 10 are preferably equipped with yarn retaining detents or projections M as in the previous figures, are of a similar relatively wide blade-like construction, and are formed with tangs or mounting portions 15 for individually removably assembling or disassembling them in the reed.

In Figs. 11 and 12, as compared with Figs. 15 and 16, the reed and the transfer comb 53 are shown in their elevated position, after the winding operation, which they assume in applying the transfer comb. During the winding operation, both the comb and the reed are in the normal or lowered position of Figs. 15 and 16, in which only the upper winding-guide portions 'H of the reed dents are in cooperative guiding relation with the yarns, as indicated by the dotted line position of the dents in Fig. 11. The cross bar 25, the yarn table 26, the ind-ex 48, as well as the comb holder 54, the lifter cam levers 63 and their pivotal supports 64. as well as other parts not necessary to mention specifically. may be the same as in the previous figures. After winding, the comb and the reed are elevated in unison. so that the offset or intermed ate inclined parts 12 of the reed dents first shift the yarns laterally to the dotted line posit n as in Fig. 14. and cause them to have t e desired s acing the same as that of the comb teeth, which then pass up between them. to

The mounting of the reed dents, for lifting in unison with the transfer comb. may be by means of a slotted mounting bar such as 33 of Figs. 3 and 4, but we have, in Figs. 11, 12 and 16, illustrated a modified form of mounting. The individual dents are formed with a reduced lower or tang portion 15 and with rear and front shoulders Hi, I! respectively, the latter adapted to seat upon the rear top portion of .the comb holder 54,

with the fore edge of the tang against the rear Wall of said holder. The dents are individually removably held in position upon the holder as by means of an attaching strip or bar 18 adapted to be applied against the rear edges of the dent tangs l and to be secured in position as by means of the screws IS. The inner face of this mounting bar may be appropriately slotted as indicated in dotted line at 80 to receive the dent tangs, to retain the dents in the desired position laterally, that is, lengthwise of the reed. The dents are additionally releasably locked, against vertical dislodgement, as by means of a longitudinally extending key 8| received in a rear locking slot 82 formed in each dent.

In the described manner, and as shown in said Figs. 11, 12, 15 and 16, the feature of individual assembly and demounting of the dents, for replacement, redistribution, or other purposes, is preserved as well as that of insuring proper guiding and application of the yarns with respect to the comb. The other novel features, including that of ready identification of any individual dent and of visual demarkation of the dents or series of them, as by the provision of markers, and the other features of Figs. 1 to 10, may likewise be embodied in connection with the form of Figs. 11 to 16.

In order that the reed dents of Figs. 11 and 12, having the ofiset provisions for redistributing the yarns in the application of the transfer comb, may also be used interchangeably, upon the same or other machines, in cases where such spreading or redistribution of the yarns is desired, the construction of the dents'themselves and of their attaching elements as well as the comb holder and associated portions of the machine itself, may be and desirably are arranged for such interchangeability.

In the latter case, that is, where no redistribution is desired, the reed is preferably mounted in fixed position upon the machine, independently of the comb holder, so that it' is not elevated with the latter. It is nevertheless desirable that the reed dents remain facing in the same direction, that is, with their fore guide portions 10a at the side toward the yarn spool. In such instance, referring now particularly to Fig. 13, the same mounting strip or bar 18, or other similar strip, is shifted to the front wall of the cross bar 25, and the rear shoulders 16 of the dents are set upon the top of said mounting strip, with the rear edges of the tangs against the front wall of the strip. The dents are there held by means of a second or front attaching strip 83, which may also be the same or a similar strip as the member 80 of Fig. 11 and may be similarly slotted as at 84 for positioning the dents laterally. In some cases the same rear locking slot 82 of the dents may be used for locking them vertically, but these rear locking notches, in the arrangement as shown in Fig. 13, become relatively inaccessible. To facilitate the locking of the dents and in order that they may be readily demountable or replaceable merely by the removal of the front strip 83, the dents are preferably provided with a second front locking notch 85 for the reception of a key 81 as in Fig. 11.

It is thus apparent, by comparison of Fig. 13 with Fig. 11, that thesame individual dents as provided for the redistributingform of Fig. 11 may also be employed in the fixed-reed form of Fig. 13, or of Figs. 1 to 10, without necessitating special forms of dents for the particular installations, and that the type of installation may readily be interchanged, from that of the lifting and redistributing reed type of Figs. 11, 12 and 14 to 16, to the fixed reed type of Fig. 13 and of Figs. 1 to 10, and the reverse. 5
